The visibility of the indicium may be enhanced by the laminate including material that is a different color than the metallic layer, and the different color being at least partially visible through the indicium.
This application is a division of U.S. patent application Ser. No. 16/647,209, filed Mar. 13, 2020, which is the National Stage of International Patent Application No. PCT/US2018/000373, filed Sep. 21, 2018, which claims the benefit of U.S. Provisional Patent Application No. 62/561,711, filed Sep. 22, 2017. Each of the above-referenced patent applications is incorporated herein by reference in its entirety.
BACKGROUNDThe present invention generally relates to packaging material and, more particularly, to packaging material that may be formed into a bag, wherein the bag may include indicium configured to be seen by viewing the inner surface of the bag.
SUMMARYAn aspect of this disclosure is the provision of a packaging material that is, or includes, a laminate. In an embodiment, the laminate includes first and second webs that are joined to one another, wherein the first web includes a metallic layer on a second layer, the metallic layer is positioned between the second layer and the second web, and indicium is defined in at least the metallic layer. In an embodiment, the packaging material is configured so that the indicium is visible from a first side of the packaging material, and the indicium is substantially not visible from a second side of the packaging material. The indicium can be at least partially defined by holes in the metallic layer. The visibility of the indicium may be enhanced by the laminate including material (e.g., ink, an interior layer, and/or other suitable material) that is a different color than the metallic layer, and the different color being at least partially visible through the indicium. The packaging material, or more specifically the laminate, can further include graphics that are visible from the second side of the packaging material.
The packaging material can be formed into a package that is configured so that the first web defines an inner surface of the package, and the indicium is positioned for being seen by viewing the inner surface of the package. For example, the package can include a seam connecting first and second portions of the laminate to one another, wherein the seam is configured to at least partially obstruct access to the interior space of the package.
Another aspect of this disclosure is the provision of a method for forming packaging material. The method can include laminating at least a first web and a second web to one another to at least partially form the packaging material. While the laminating is occurring, indicium can be defined (e.g., by laser ablation) in at least a metallic layer of the first web, wherein at least a portion of the defining can be performed at a position that is upstream from the laminating. The packaging material can be configured so that the indicium is visible from a first side of the packaging material, and the indicium is substantially not visible from a second side of the packaging material. The method can further include forming a portion of the packaging material into a package that is configured so that the first web defines an inner surface of the package, and the indicium is positioned for being seen by viewing the inner surface of the package.
The foregoing summary provides a few brief examples and is not exhaustive, and the present invention is not limited to the foregoing examples. The foregoing examples, as well as other examples, are further explained in the following detailed description with reference to accompanying drawings.
The drawings discussed below are schematic, and features depicted therein are not drawn to scale. The drawings are provided as examples. The present invention may, however, be embodied in many different forms and should not be construed as limited to the examples depicted in the drawings.
Examples of embodiments are disclosed in the following. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. For example, features disclosed as part of one embodiment can be used in the context of another embodiment to yield a further embodiment.
In one embodiment of this disclosure, after the packaging material 12 is formed, it can be converted into packages such as, but not limited to, bags (e.g., see bag 70 of
As an example, packages of this disclosure may be used in a sweepstakes contest or other suitable contests. A variety of contests are within the scope of this disclosure. For example, at least one of the indicia 18 can be a unique, predetermined identifier (e.g., number) that may be at least indirectly associated with one or more prizes. As a more specific example, the unique, predetermined identifier 18 may qualify the consumer in possession thereof to be entered into a contest associated with one or more prizes. It is believed that the contest may be like a lottery, raffle, and/or other suitable system for providing one or more prizes.
In an alternative embodiment, it is believed that the indicia 18 being substantially not visible from the exterior of the package may include some aspects of the indicia 18 being partially visible from the exterior of the package (e.g., to a user (e.g., consumer) with a naked, bare or unaided eye), wherein any such visibility is masked or obscured to a sufficient degree that the information conveyed by the indicia (e.g., the predetermined identifier) is not discernable (e.g., not discernable to a user (e.g., consumer) with a naked, bare or unaided eye). A variety of differently configured packaging materials 12 and packages are within the scope of this disclosure. For example, a wide range of indicia 18 are within the scope of this disclosure, as discussed in greater detail below.

As one example, the interior polymeric film 34 can be a transparent and/or translucent polypropylene film. As other examples, the interior polymeric film 34 can comprise polyester or any other suitable material. As further examples, the interior polymeric film 34 can comprise bio-based materials (e.g., organic bio-based materials) such as, but not limited to, polylactic acid (PLA) and/or other suitable biodegradable and bioactive thermoplastic aliphatic polyesters derived from renewable resources. The interior polymeric film 34 can be transparent, translucent, at least partially opaque, colored and/or have any other suitable characteristics. The interior polymeric film 34 can be replaced with one or more other suitable materials, for example paper or any other suitable layer. The optional heat-sealable layer 32 (e.g., a layer of thermoplastic polymeric material that typically is transparent and/or translucent) can be on the opposite side of the interior film 34 from the metallic layer 20, so that the interior film 34 is positioned between the metallic layer 20 and the heat-sealable layer 32.
In the example depicted in
The laser head 40 can be operatively associated with (e.g., at least partially controlled by) a computerized controller 44. As will be discussed in greater detail below, the laser head 40 can be operated to form a series of the indicia 18 that are spaced apart from one another in the lengthwise direction of the first web 14. There can be a series of similarly operating laser heads 40 spaced apart from one another in the direction crosswise to the machine direction (“crosswise direction”).

Alternatively, the second web 16, including its eye marks, may be configured in any other suitable manner. For example, the film 50 can be replaced with one or more other suitable materials, for example paper or any other suitable layer. For the film 50 or its replacement (e.g., paper or other suitable material), at least some of the ink 52, if present, may be on the outer side of the film 50 or its replacement. Optionally, any such outer ink 52 may be covered with a protective layer or coating (e.g., overlacquered). The film 50 may be replaced with one or more suitable materials in various combinations.
In the example depicted in
The laser head 40, controller 44 and optical sensor 56 can be configured (e.g., by way of a computer processor, computer memory and computer software of the controller) so that the position of each indicia 18 can be precisely controlled in a predetermined manner. As one example for the embodiment in which the packaging material 12 is formed into packages, each package can include only one of the indicia 18, and that indicia can be located at a predetermined position in the package. For example, if desired, the indicia 18 can be placed in register with (e.g., superposed with) predetermined corresponding print defined by the ink 52. Alternatively, more than one indicia 18 can be included in each package.

In contrast to
In the embodiment depicted in the drawings, the indicia 18 is typically substantially not visible from the second side 64 of the packing material 12 because, for example, the laser head 40/laser beam is restricted (e.g., prevented) from distorting (e.g., forming the indicia 18 in) the second web 16. For example and as depicted in
At least partially reiterating from above with reference to
In another embodiment in which the interior polymeric layer 60 is transparent and/or translucent, the indicia 18 may be substantially not visible through the first side 62 of the packaging material 12 when the packaging material 12 is not illuminated from behind (e.g., when light is not shining onto the second side 64 of the packing material). On the other hand, in the embodiment in which the interior polymeric layer 60 is transparent and/or translucent, the indicia 18 may be visible through the first side 62 of the packaging material 12 when the packaging material 12 is illuminated from behind (e.g., when light is shining onto the second side 64 of the packing material). Accordingly, a method of this disclosure can include viewing the indicia 18 through the first side 62 of the packaging material 12 while illuminating (e.g., shining light onto) the second side 64 of the packing material. The method can include the indicia becoming visible, or at least further visible, through the first side 62 of the packaging material 12 in response to the illuminating of the second side 64 of the packing material.
In a further embodiment in which the interior polymeric layer 60 is transparent and/or translucent, predetermined portions of the ink 52 superposed with the holes 46 may be at least partially visible, by way of the holes 46 in the metallic layer 20, through the first side 62 of the packaging material 12 to at least partially define the indicia 18. As an example, dashed lines in
The predetermined ink portions 68 can be positioned between the interior polymeric layer 60 and respective portions of the ink 52 that define the one or more graphics (e.g., see graphics 72 of
As an example,
The bag 70 can be formed by folding the piece of packaging material 12 onto itself, so that respective marginal portions of the heat-sealable layer 32 are in opposing face-to-face contact with one another, and heat and pressure can be applied to those marginal portions to form the seals 74, 76. Alternatively, the heat-sealable layer 32 may be omitted, and the seals 74, 76 can be formed using a cold-seal adhesive, or in any other suitable manner. The package, or more specifically the bag 70, can completely enclose one or more articles (e.g., food products or any other suitable articles) in a hermitically sealed manner.
In the example of
As an example, the laser head 40 can include or otherwise be associated with a pulsed fiber laser, or any other suitable laser. The system 10 can be operated with the laser system deactivated when the inclusion of the indicia 18 in the packaging material 12 is not desired.
The controller 44 can comprise at least one digital computer including, for example, one or more of each of a central processing unit or processor, computer hardware integrated circuits or memory, data storage, and/or equipment interfaces. For example, the equipment interfaces of the controller 44 can be respectively operatively associated with the laser 40, optical sensor 56, and/or other suitable features. As another example, one or more of the equipment interfaces of the controller 44 can be operatively associated with one or more user interfaces configured to allow a user to provide commands and information to the controller, and configured to allow the controller to output information to the user. For example, the input-type feature(s) of the user interfaces can include a keyboard, a cursor control device (e.g., a mouse), a visual display with touch functionality (e.g., capacitive or other sensors that are configured to detect physical contact), and/or any other suitable devices. As additional examples, the output-type feature(s) of the user interfaces can include a display device (e.g., a monitor or projector), speaker, and/or any other suitable devices. The controller can be in the form of a distributed computing system; therefore, the features of the system controller can be spread between separate computers. Features of the controller, user interfaces, and/or other associated devices may be implemented in various manners, including software, hardware, firmware, or any combinations thereof, for facilitating respective aspects of this disclosure.
In other embodiments of this disclosure, the packaging material 12 can include one or more different, additional, or less layers of material. For example and at least partially reiterating from above, the heat-sealable layer 32 and/or ink(s) 52 can be omitted. As another example, it is believed that the metallic layer 20 can be replaced with and/or supplemented with one or more other types of materials that are susceptible to being laser marked and/or laser engraved by the laser beam projected from laser head 40. More generally, it is within the scope of this disclosure for the indicia 18 to be defined in predetermined layer(s) (e.g., the metallic layer 20 and/or other suitable layer(s)) of the packaging material 12 by laser marking and/or laser engraving the predetermined layer(s) with the laser beam projected from laser head 40.
In the specification and/or figures, examples of embodiments have been disclosed. The present invention is not limited to such exemplary embodiments. Unless otherwise noted, specific terms have been used in a generic and descriptive sense and not for purposes of limitation. The use of the term “and/or” includes any and all combinations of one or more of the associated listed items.
